2.the heat energy from the water makes the gas inside the bottle move faster and spread further apart mixing with the cold water along the way and creating purple water
3.Hot molecules move more than cold molecules, and things that are hot typically take up more space than the same things when they are cold
4.heat energy in a liquid or gas move and take the place of particles with less heat energy
